[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0047] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.
[0048] Before describing the embodiments of the present application, a brief introduction to the prior art is first given.
[0049] The refined management of high-value consumables has become a key point. The SPD model (Supply, Processing, Distribution) is a supply chain management model with hospital medical supplies management as the core. It realizes the refined management of material supply through information technology and process optimization, and is an important part of the hospital's digital transformation. In the SPD model, the SPD platform is connected and integrated with multiple systems such as the supplier platform, the hospital HIS (Hospital Information System), and the Sunshine Procurement Platform. The physical warehouse under the SPD model is usually called a "primary warehouse" or a "central warehouse". After the various departments of the hospital successfully apply for it on the SPD platform, the relevant personnel will place it on the shelves in the department's consumables room.
[0050] High-value consumables in hospitals typically refer to relatively expensive, expendable medical devices that require extremely high safety requirements, strict production and usage controls, and high prices. These consumables are typically used directly on the human body, in clinical operating rooms, interventional suites, and other settings, requiring strict management at every stage, from production and procurement to distribution and use. Managing high-value consumables presents challenges, including a wide variety of products, complex specifications, and significant risks. Traditional manual management methods rely on manual paper records of incoming and outgoing inventory, manual inventory counting, Excel-based statistical data, and billing through the scanning of QR codes for each item after consumption.
[0051] The traditional manual management model has the following defects:
[0052] 1. Economic losses: The traditional manual management model has defects such as weak control over the entire process, extensive inventory management, and insufficient informationization. This can easily lead to inaccurate basic data, loss of consumables, missed billing, and incorrect billing. High-value consumables usually cost hundreds to tens of thousands of yuan, which will cause economic losses to the hospital.
[0053] 2. Low management efficiency: Manual registration, manual inventory, and manual scanning and accounting are time-consuming and labor-intensive. The operation of processes such as procurement, storage, retrieval, return, and use cannot be closely coordinated among multiple parties such as industry chain suppliers, national medicine operators, and hospitals. There is information asymmetry on current inventory quantity, quantity to be replenished, expired consumables, consumables nearing their expiration date, and consumables to be returned.
[0054] 3. Difficulty in query and tracing: If consumables are lost, the only way to trace the person who took them is to rely on the medical staff's memory or check the duty roster and other clues.
[0055] Due to the busy schedules of medical staff and the critical nature of clinical surgeries, hospitals have a high-demand demand for fast consumable storage and retrieval, automated recording, and accurate data. Therefore, hospitals urgently need to leverage information technology to implement automated consumable storage and retrieval, intelligent reminders, automatic inventory, and statistical analysis. This will enable unattended operation, improve the efficiency of high-value consumable management, and empower hospitals to transform into modern hospitals.
[0056] The present invention provides a high-value consumables management method and system based on the SPD mode, which aims to solve the pain points such as economic losses, low management efficiency, and difficulty in query and tracing in the process of high-value consumables management, and changes the traditional manual management mode with the help of information technology.
[0057] At present, the RFID smart cabinet hardware products and supporting software management systems on the market only provide simple functions and require secondary development to be successfully implemented and truly meet user needs. The accurate grasp of product positioning, needs and pain points, and the design of system processes are the key to determining the success of RFID smart cabinet products. The present invention combines RFID smart cabinet hardware products with software management systems (such as Figure 7 ) to achieve traceability of the entire life cycle of consumables and unmanned storage and retrieval processes.
[0058] like Figure 1 As shown, an embodiment of the present invention provides a high-value consumables management method based on the SPD mode, which includes the following steps:
[0059] S1, transmits the basic information fields of consumables to the SPD platform through the manufacturer platform.
[0060] S2, transmits basic information of consumables and hospital-compiled batch information to the high-value consumables management platform through the SPD platform.
[0061] Preferably, the specific method of transmitting basic information of consumables and hospital-compiled batch information to the high-value consumables management platform through the SPD platform includes: the SPD platform makes a label after receiving the basic information field of the consumables, writes the basic information field of the consumables plus the hospital-compiled batch field into the RFID chip tag through the RFID reader / writer device, and affixes the label to the outer packaging of the consumables.
[0062] S3, transmits the estimated cost of consumables taken out from the smart cabinet to the HIS platform through the high-value consumables management platform;
[0063] S4, transmit the binding information of patients and consumables to the high-value consumables management platform through the HIS platform, and take out unused consumables to be returned;
[0064] S5: The high-value consumables management platform transmits the consumables-related information stored in the smart cabinet to the SPD platform. The consumables-related information includes user access records, replenishment information, expiration information, inventory information, etc.
[0065] Preferably, the high-value consumables management method further includes: obtaining the user's login status in the smart cabinet, and automatically controlling the opening state of the smart cabinet door according to the login status.
[0066] like Figure 2 As shown, the high-value consumables management method also includes: S6, transmitting damaged, contaminated consumables to the manufacturer's platform through the SPD platform for return and refund.
[0067] Preferably, if Figure 2 As shown, the high-value consumables management method also includes a replenishment algorithm, specifically including:
[0068] S7, obtaining the minimum inventory requirement quantity Cmin(i) of the i-th specification and model of consumables;
[0069] S8, obtaining the current total inventory quantity Creal(i) in the smart cabinet;
[0070] S9, obtaining the quantity to be replenished Csupply(i)=Cmin(i)-Creal(i) according to the minimum inventory requirement quantity of the consumables and the current total inventory quantity.
[0071] The high-value consumables management method also includes a pending return algorithm, which specifically includes: when a consumable is taken out from the smart cabinet according to the patient number, the initial value of the consumption status mark is Scon=1; when the consumable is not used in the operating room and the HIS platform is marked as unconsumed, Scon=0; the life cycle status of the consumable is marked as pending return.
[0072] The high-value consumables management method based on the SPD model integrates the manufacturer platform, SPD platform, high-value consumables management platform and HIS platform, and uses information technology to change the traditional manual management model. It can achieve traceability of the entire life cycle of consumables and unmanned storage and retrieval process, helping hospitals to reduce costs and increase efficiency in the refined management of high-value consumables. It solves the problems of the traditional manual management model due to weak overall process control, extensive inventory management, insufficient degree of informatization, etc., which easily lead to inaccurate basic data, loss of consumables, missed billing, and wrong billing.
[0073] As a preferred technical solution, an embodiment of the present invention provides a high-value consumables management method based on the SPD mode, such as Figure 6 As shown, the specific process includes:
[0074] S1, the manufacturer platform delivers the consumables purchased by the hospital to the SPD primary warehouse, and synchronizes the basic information fields of the consumables to the SPD platform.
[0075] S2: After receiving the consumables, the SPD primary warehouse will label them. That is, the basic information field of the consumables plus the hospital's self-compiled batch field will be written into the RFID chip tag through the RFID reader and writer device, and the tag will be affixed to the outer packaging of the consumables;
[0076] S3: After receiving the replenishment information pushed by the high-value consumables management platform, the delivery personnel of the SPD primary warehouse prepare the corresponding consumables and send them to the hospital's high-value consumables management secondary warehouse;
[0077] S4: The delivery person logs into the RFID smart cabinet. To accurately open doors and improve access speed, the high-value consumables management platform automatically determines which door to open based on whether the user is logged in to the main cabinet or the auxiliary cabinet. If logged in to the auxiliary cabinet, the independent door will be opened. If logged in to the main cabinet, after clicking the save menu, the default is to open all doors within the specified time. The screen interface allows users to modify the settings.
[0078] S5: After successful login authentication, the door is opened and video surveillance is activated. The delivery person stores the consumables in the RFID smart cabinet.
[0079] S6: After the door is closed, the inventory is automatically triggered. The RFID smart cabinet automatically identifies the consumables deposited by the delivery person in batches through the built-in RDIF module. The status of the consumables is set to "deposited" and the consumables are bound to the delivery person's operation information for easy subsequent query and traceability.
[0080] S7, after the operation record is saved in the database, the storage operation is completed.
[0081] S8. The doctor writes an order for the consumables required by the patient on the hospital HIS platform, and the system synchronizes the patient information to the high-value consumables management platform.
[0082] S9, the person who takes out the consumables logs in to the RFID smart cabinet, and video surveillance is started after the authentication is passed. In order to accurately open the door and improve the access speed, the high-value consumables management platform will automatically determine which door to open based on the user's login status in the main cabinet or the sub-cabinet. If you log in on the sub-cabinet, the independent door will be opened. If you log in on the main cabinet, the user selects a patient on the screen and clicks it. A pop-up window will appear with the consumables required for the operation under the patient. After selecting the consumables to be taken, the high-value consumables management platform will accurately and automatically open the cabinet door where the consumables are located; if you select "take directly without a patient" on the screen, the door will be fully opened by default within the specified time, and the screen interface allows users to modify it;
[0083] S10, open the door, and the consumables removal personnel take out the required consumables from the RFID smart cabinet;
[0084] At step 11, inventory is automatically triggered after the door is closed. The RFID smart cabinet automatically identifies the consumables removed by the operator in batches through the built-in RDIF module, and the consumable status is removed. If the user selects "Remove by patient number," the consumables are bound to both the operator and the patient number during inventory. If the user selects "Remove directly without patient number," the consumables are bound only to the operator during inventory. After consumption is confirmed in the operating room, the patient number information is transmitted back to the high-value consumables management platform, which automatically completes the binding of the consumables to the operator and patient number for subsequent query and traceability.
[0085] Here, by binding the logged-in user and the patient number at the same time, the method can not only reduce the loss of consumables under abnormal circumstances, but also provide more clues to assist in rapid tracing and searching, thereby reducing the risk of loss.
[0086] S12, in order to avoid economic losses caused by medical staff manually using a scanner to scan and bill consumables one by one after they are consumed in the operating room, after the closed inventory is completed, the consumables list will be taken out and synchronized to the HIS platform, and entered into the "Confirmed Consumed Consumables List Table" to generate estimated costs.
[0087] Here, after the consumables are taken out and the smart cabinet is closed, an estimated billing list is generated and synchronized to the HIS platform, which solves the problem of missed billing when manual scanning is done one by one with a scanner.
[0088] S13, after the operation record is saved in the database, the retrieval operation is completed;
[0089] S14: After the operating room patient consumes consumables, the consumable status is "consumed", and a billing list needs to be generated. During the manual review process, if medical staff finds that consumables have been taken but not consumed, they can manually adjust the list from the "Confirmed Consumed Consumables List" to the "Unconsumed Consumables List". After the adjustment, the system detects the change in consumption status and automatically generates a pending return message to remind relevant personnel to return the consumables to the RFID smart cabinet to avoid loss. At this time, the consumable status is "pending return";
[0090] S15: If consumables are found to be soiled or damaged after opening the packaging in the operating room, medical staff will submit a "return" request to the manufacturer on the SPD platform. At this time, the consumables will be in the "pending return" state.
[0091] S16: After the manufacturer agrees to return the consumables on the SPD platform, the status of the consumables is "returned";
[0092] S17, the process ends here.
[0093] like Figure 3As shown, an embodiment of the present invention provides a high-value consumables management system based on the SPD mode, which is used to implement the high-value consumables management method based on the SPD mode, which includes a manufacturer platform, an SPD platform, a high-value consumables management system and an HIS platform.
[0094] The manufacturer platform is used to transmit basic information fields of consumables to the SPD platform; the SPD platform is used to transmit basic information of consumables and hospital-compiled batch information to the high-value consumables management platform.
[0095] The high-value consumables management platform is used to transmit the estimated cost of consumables taken out from the smart cabinet to the HIS platform, and to transmit the consumables-related information stored in the smart cabinet to the SPD platform; the HIS platform is used to transmit the binding information of patients and consumables, and the excess unused consumables to be returned to the high-value consumables management platform.
[0096] The SPD platform is also used to transmit damaged and contaminated consumables to the manufacturer platform. The consumables-related information includes user access records, replenishment information, expiration information, inventory information, etc.
[0097] Preferably, the high-value consumables management system also includes an intelligent cabinet control module and an algorithm module.
[0098] The smart cabinet control module is used to obtain the user's login status in the smart cabinet and automatically control the opening status of the smart cabinet door based on the login status. The algorithm model is used to obtain the minimum inventory requirement quantity Cmin(i) of the i-th specification and model of consumables and the current total inventory quantity Creal(i) in the smart cabinet. Based on the minimum inventory requirement quantity and the current total inventory quantity of the consumables, the replenishment quantity Csupply(i) = Cmin(i) - Creal(i) is calculated.
[0099] like Figure 4 as well as Figure 5 As shown, the high-value consumables management system also includes:
[0100] (1) Login authentication module: supports 4 login authentication methods, including face recognition authentication, finger vein recognition authentication, high-frequency IC card authentication, and account password authentication.
[0101] (2) Deposit module: After the user passes the authentication, the cabinet door is opened. After the deposit is made, the door is closed and the inventory is automatically triggered. The RFID technology built into the smart cabinet automatically identifies the consumables taken this time in batches, completes the binding relationship between the consumables and the depositing user, and simultaneously starts the surveillance camera until the door is closed.
[0102] (3) Removal module: After the user passes the authentication, the cabinet door opens and the user can take out the required consumables according to the patient number (the doctor has already issued the required consumables for the patient on the HIS platform), or directly take out the consumables if there is no patient number. After taking out, closing the door automatically triggers an inventory. The RFID technology built into the smart cabinet automatically identifies the consumables taken in batches, completes the binding relationship between the consumables and the user who took them out, and simultaneously activates the surveillance camera until the door is closed.
[0103] (4) Intelligent reminder module: including reminders for replenishment, expiration, and return, etc., automatically forming an efficient operation mechanism for the industrial chain.
[0104] (5) Query and traceability module: For consumables with surplus or shortage, the system provides multiple query and traceability methods, including surveillance video tracing, log tracing, and access record tracing, so as to facilitate quick retrieval.
[0105] (6) Statistical analysis module: Real-time statistics of current inventory and historical storage of consumables, providing more scientific data support for procurement and stocking.
[0106] (7) Parameter setting module: Users can set the upper and lower limits of the inventory in the RFID smart cabinet, and the system will automatically issue an early warning to facilitate timely replenishment of the SPD primary warehouse.
[0107] Specifically, the high-value consumables management system involves the manufacturer platform, SPD platform, and HIS platform. The process includes procurement, replenishment of the first-level warehouse, entry into the second-level warehouse, withdrawal from the second-level warehouse, consumption and other links. The status of consumables is stored in the smart cabinet, withdrawn, consumed, to be returned, to be returned, and returned.
[0108] To sum up, the high-value consumables management system based on the SPD model realizes the automation of the entire process of high-value consumables from procurement, distribution, replenishment, shelving, removal, return, consumption, inventory, etc. by connecting and integrating the manufacturer platform, SPD platform, HIS platform and high-value consumables management platform.
[0109] As a preferred technical solution, the high-value consumables management based on the SPD mode also includes a data acquisition module and a neural network module.
[0110] The data collection module is used to collect inventory data (current inventory quantity, expiration date, and location) in real time through scanning with the ultra-high frequency RFID reader of the smart cabinet. The SPD platform is also used to integrate historical consumption data (including but not limited to department usage frequency data, surgical scheduling data, and seasonal fluctuation data).
[0111] For department usage frequency data, the SPD platform can interact with the HIS platform and the department's secondary library (high-value consumables smart cabinet) in real time to record the daily / weekly / monthly consumables consumption of each department, including specific specifications, batch numbers, expiration dates, etc.; for surgical scheduling data, the SPD platform can be connected to the operating room management system to record the consumables usage list for each operation (such as heart stents, joint prostheses, etc.), and the scheduling time-related data include the operation date, duration, and surgeon's preferences (such as the use of specific brands of consumables); for seasonal fluctuation data, it mainly includes: 1. Epidemic cycle data: for example, the high incidence of respiratory diseases in winter leads to a surge in the consumption of respiratory consumables (such as nebulizer tubing); 2. Impact of holidays: the number of elective surgeries decreases by 30%-50% before and after the Spring Festival, while the demand for emergency consumables (such as trauma repair materials) increases; 3. Policy and procurement cycle: Adjustments to medical insurance cost control policies may lead to the replacement of consumable brands, and data fluctuations during the transition period of substitute consumption are recorded.
[0112] The neural network module can be an LSTM neural network. The LSTM neural network is used to predict consumables consumption over the next seven days. Input features include historical consumption data and inventory data. For training the LSTM neural network, three years of historical inventory and consumption data can be used as output, along with a seven-day rolling forecast.
[0113] Since collecting training data sets to train neural network models is a conventional technical means in this field, it will not be described in detail here.
[0114] When the smart cabinet detects that the inventory in the secondary warehouse is below the threshold, it automatically triggers the SPD platform to generate a replenishment order and prioritizes delivery to high-consumption departments; the neural network module updates parameters at the end of each month to learn actual consumption and prediction errors and optimize future prediction accuracy.
[0115] Based on the data acquisition module and the neural network module, the replenishment process in one embodiment of the present invention is as follows:
[0116] 1. Real-time inventory monitoring: The smart cabinet synchronizes inventory data to the SPD platform every hour to calculate the current total inventory (central warehouse + department secondary warehouse); if the current inventory ≥ the minimum inventory requirement (safety stock), replenishment will not be triggered for the time being.
[0117] 2. Dynamic replenishment decision-making: When the current inventory is less than the minimum inventory, the LSTM model is used to predict consumption over the next seven days. The replenishment quantity is calculated as: replenishment quantity = max(safety stock - current inventory, predicted consumption × (1 + α) / replenishment cycle). α is the safety factor, which is dynamically adjusted based on the supplier's delivery reliability. When inventory is nearing its expiration date, consumables with near-expiration dates are consumed first, triggering an emergency replenishment process.
[0118] For the safety factor, a benchmark value can be set based on a hierarchical control strategy, as shown in the following table:
[0119] Consumables risk level Clinical importance α reference value Dynamic Range Category 1 (heart stents, etc.) Very high 0.3 ±0.1 Category II (artificial joints, etc.) high 0.2 ±0.05 Category 3 (stapler, etc.) middle 0.15 ±0.03
[0120] For consumables nearing their expiration date, the remaining shelf life (T) attenuation factor is introduced to obtain a safety factor α = α 基准 ×e -k / T Where e represents a natural constant and k represents the attenuation coefficient. The closer the expiration date, the smaller the value of α to accelerate turnover. Preferably, the safety factor α is recalculated weekly using a sliding window mechanism to maintain parameter timeliness.
[0121] 3. Multi-objective optimization: Use genetic algorithm to balance cost (purchasing / warehousing) and out-of-stock risk, with the objective function being min(C 采购 +C 仓储 +λ×out-of-stock cost); where λ represents the risk weight coefficient, which can be set by technical personnel, C 采购 =Replenishment quantity×unit price×(1-discount rate), C 仓储 =Inventory quantity×(storage rate+fund interest rate×unit price). The storage rate refers to the hospital's storage area cost, and the fund interest rate is calculated based on the bank's benchmark loan rate. The out-of-stock cost is defined as the hidden costs such as surgery delays and patient complaints caused by insufficient inventory.
[0122] Preferably, the risk weight coefficient λ is dynamically adjusted according to the urgency of the department, such as the ICU out-of-stock risk weight coefficient λ = 0.8, and the general department λ = 0.3.
[0123] The objective function integrates the dimensions of inventory, cost, and risk, and has the following beneficial effects:
[0124] 1. Cost control: This is directly related to inventory holding costs (such as capital occupation and storage space) and procurement costs, avoiding capital waste caused by overstocking.
[0125] 2. Risk quantification: The tolerance for out-of-stock risk can be dynamically adjusted through the risk weight coefficient. For example, in the scenario of emergency supplies, λ can be increased to reduce the risk of patients waiting.
[0126] 3. Decision Compass: Transforms the complex requirements of hospital management (cost, efficiency, and risk) into a computable and optimizable logical framework. By dynamically adjusting risk weight coefficients, the objective function can adapt to the personalized needs of different scenarios, such as operating rooms and interventional rooms, ultimately achieving refined operations under the SPD model.
[0127] In summary, the high-value consumables management method and system based on the SPD model described in the present invention, based on in-depth research on user needs, relies on innovative design highlights such as multi-platform integration and docking under the SPD model, closed-door prepayment model, simultaneous binding of users and patients, and fast interactive process, and has the following advantages and practical value:
[0128] 1. Reduce economic losses: The closed-door pre-billing model avoids the problem of missed billing when manually scanning one by one with a scanner; consumables are bound to patient information when they are taken out, avoiding the problem of wrong billing; the system's built-in algorithm model intelligently reminds consumables to be returned, avoiding the problem of lost consumables; it provides multi-threaded query and tracing such as video surveillance query, door opening log query, access record query, etc., so lost items can be recovered.
[0129] 2. Full-process traceability: Each consumable can be traced back to the manufacturer and to the individual patient. The entire process can be managed and tracked using a one-item-one-code quality management system, improving management capabilities in all aspects.
[0130] 3. Reduce medical risks: Intelligent near-expiration reminders and expired warnings reduce medical safety risks during material use.
[0131] 4. Improve management efficiency: Based on the multi-system integration and docking under the SPD model, the operation of the procurement, storage, retrieval, return, use, and refund processes is seamlessly coordinated among industry chain suppliers, national medicine operators, hospitals, and other parties. The business process is solidified and the consumables management system is standardized; the statistical analysis function makes hospital decision-making more efficient.
[0132] 5. Achieve fast access: Compared with similar competing products on the market, this system has a good user experience design through precise door opening, estimated door closing fee, four login methods, etc., making it more convenient and time-saving for users to access consumables.
